PRINTING MACHINE Filed March 10, 1954 v 2 Sheets-Sheet 2 VIII/[Ill Patented Mar. 17, 1936 Iran STATES The present invention, relates to means for i aillustrating and coating articles such as papencardboard, leather, celluloid, cellophane, glass, tin, metal, silk, cotton and other fabrics and materials. It has particular reference to a machine'ior spraying a covering coat of suitable color.

In order to provide paper and similar fabrics or materials withta plurality of coatings of any desiredcharacter it is necessary to use a printing,

painting, spraying or like process to cover the surface. Such operations may be very expensive to carry out by means of machines as at present constructed or by hand on a large scale because of the handling required, the necessity for applying. a coating evenly, of rotating the article, drying,. etc. The present invention provides a machine Y which is capable of performing various operations 20, automatically.- The machine is constructed to rewiv'e-paper and similar fabrics or materials fed to it by any suitable mechanism, or manually, to hold the paper and similar fabrics or materials, to move the table over a prescribed opening 25 wherein the coating is applied, to rotate the table, to manipulate the coating-applying means so that the paper and similar fabrics or materials areproperlycoated, to retain the paper and similar fabrics or materials, preferably until the coating 30 is dried, then to release the paper and similar fabrics or materials for removal either by suitable mechanism or manually, thus forming a continuously operating machine capable of high production with-a minimum of care and attention.

35 Onebbiect of .the invention is the provision of a machine having a rotating table for receiving,

holding and manipulating an article to be printed or coated.

Another object is the provision of such a rotating table provided with a plurality of openings materials by means of magnetism to enable a clean and clear impression to be reproduced on the {paper or similar fabrics or materials. 55- Still another object of the invention is the provision of a. travelling coat-applying device capable of motion to cover any predetermined portion, or all of the surface, of the paper or similar fabrics or materials to be printed or coated.

Still another object of the invention is the pro- .5 vision of means to' manipulate or revolve the paper or similar fabrics or materials for properly presenting its surface for application of the printing or coating.

Another object of the invention is the combina- 10 tion of some or all of the foregoing features into a single machine as defined in the appended claims.

In the accompanying drawings I have shown a machine which combines all of the various 15- features above referred to and many other and ancillary features which contribute to the proper functioning of the machine. The machine of the drawings is given by way of example to explain the nature of the invention and it is not to be considered as a limitation of the invention to the particular machine described and illustrated. Although the machine of the drawings is specifically adapted to print or coat on paper or similar fabrics or materials, it is to be understood that modifications and changes are contemplated for other uses of the machine, as will appear from the scope of the appended claims.

Other. objects, advantages, and features 9f invention may appear from the accompany tl drawings, the subjoined detailed description, and the appended claims.

In the drawings V Figure 1 is a half plan view of my machinath e" other half being broken away to show the structure below. Figure 2 is a fragmentary,- sectional view of the table top, taken on line 2-2 of Figure 1.

Figure 3 is a side elevation of niy machine. Figure 4 is a fragmentary, sectional View 40 the line of Figure 1. Figure 5 is a transverse sectional view of spray gun actuating device.

Referring'more particularly to the a a-s.-

in general, the machine comprises a mog member I, such as a rotating table or disc. .A plurality of openings 2 are cut thru the table 6' and these openings are equidistantly spaced around the table, for a purpose to be further described. Around each opening 2, I provide a holding frame 3, the purpose of these frames-is to securely clamp a stencil over each of the open: ings. The stencils being cut from a pie metal. Each stencil has the peculiar pattern or configuration cut thereon which conforms to the particular color which it is desired to apply therewith. All of which is usual and well known in the art.

The table I is rotatably mounted on a central pedestal 4, and the table is also tiltable, as will be further described. A spider 5 is secured to the table at the center thereof, and a pin 6 extends into the spider and is secured in a central dome 1. The pin 6 rests on a ball thrust bearing 8 so that the table can easily rotate. A pair of bearing hangers 9-9 extend upwardly from the pedestal 4, and a tilting frame I0 is journaled in the hangers 9. The pin 6 also extends into the tilting frame I0, thus securely centering the table I.

An operating arm II extends from the tilting frame I0 and this frame is tilted in the following manner: A foot treadle I2 is pivotally mounted to the pedestal 4 adjacent the bottom thereof, and a rod I3 extends upwardly from the treadle I2 to a spring I4, which spring is secured or attached to the outer end of the arm II. Thus it will be evident that when the treadle I2 is depressed by the foot of the operator, the entire table I will be tilted in the bearings 9-9 and the purpose of this tilting operation will be further described. When pressure is released from the treadle I2, it is necessary to return the table I to a horizontal position, and this is accomplished by a rubber belt I5 which extends over a post I6 which projects rearwardly from the tilting frame Ill. A post I1 also projects from the pedestal 4 and the belt I5 encircles this latter post as well as the post I6. A stop block I8 rises from the top of the pedestal 4 and the post I6 is adapted to strike against this block thus holding the table I accurately in horizontal position. It is, of course, understood that the entire frame I0 and attached parts do not rotate. The table I moves in a rotary manner independent of this frame and upon the pin 6.

The table is held in tilted position by means of a catch bar I9 which is pivotally mounted to the pedestal 4 and engages an abutment 20 when the treadle I2 is depressed. A releasing link 2| is pivotally mounted in the treadle I2 and is adapted to engage the catch bar I9 when depressed by the foot of the operator. A supporting bracket 22 is secured to the pedestal 4 adjacent the top thereof, and this bracket projects forwardly.

Removably mounted on the outer end of the bracket 22 is an electro-magnet 23. This electromagnet is constructed substantially as disclosed in my co-pending application for Electro-magnet for printing machines and the lie, Serial Number 535,396. A trough or groove 24 is provided around the upper periphery of the magnet 23 for the purpose of transmitting the vacuum which is created in a pump 25. A hose, or hoses 26 extend from the vacuum pump 25 to the grooves 24 thus creating a partial vacuum which will securely and tautly hold paper, cloth, or otheris fed to the electro-magnet, thus energizing the same and the metal stencil is attracted and held closely upon the material to be worked upon. An arm 21 of the central spider 5, extends centrally of each of the openings 2, and these arms are also radially arranged. The outer end of each arm is bifurcated as shown at 28, and the table I is provided with a hole 29 immediately below the bifurcation 28. An aligning pin 30 projects upwardly from a bracket 3| which is attached to the top of the pedestal 4. The aligning pin 30 extends upwardly thru the opening 29 and between the bifurcations 28 when the table top is tilted, thus the openings 2 are accurately positioned above the electro-magnet. A spring pressed plunger 32 bears against the bottom of the table I to act as a brake so that the table will not swing too freely.

As previously stated, the metal stencil is held by the magnet securely against the material to be printed or colored, and the paint or coloring material is then sprayed or otherwise carried thru the stencil and upon the surface of the paper, or the like.

In the present instance I prefer that the color shall be sprayed on thru a suitable gun which may be either automatically or hand operated. Trays 33 and 34 are provided, and the operator may place his various spray guns containing the difierent colors upon these trays while the table is being manipulated. All that is necessary for the operator to do is to feed the paper on to the top of the electro-magnet where it is held by the vacuum from the pump 25.

The foot treadle I2 is then pressed which tilts the table and the stencil is moved on to the paper. The tilting movement of the top closes the electrical circuit and the electro-magnet is energized so that the metal stencil is securely held on the paper. The color is then sprayed thru the stencil, the treadle I2 is subsequently released and the next stencil is moved into position. This process continues until all of the stencils required have been brought into position over the paper to be printed and have been sprayed thru. A quick drying color coating may be used so that no time need be lost in waiting for the material to dry before the next stencil is placed in position.

It is to be understood that various changes in construction may be made in the machine for effecting the purposes of. this machine, and for adapting it to articles and coatings of diiferent natures as will be evident from the scope of the invention as defined in the appended claims.

In Figure 5, I have shown a device for quickly oscillating the spray gun within a limited range over the stencil mounted in the table I, as previously described. A fitting 35 is provided into which a spray gun of usual and well known design is mounted. A hose 36 extends to the fitting 35 so that air is fed to the spray gun in the usual and well known manner, or the hose may feed the liquid coating material along with the air to the gun.

A rciprocating carrier 31 in the form of a ring m-ructure is guided in its reciprocation upon a rod 38 which rod is secured in frame plates 3939. The frame plates rise from a base 40 which may be suitably mounted adjacent to the table and in such a position that the spray gun extends over the stencils. The carrier 31 has a depending bearing M which encircles the rod 38, thus guiding the carrier in its movement.

A cam cylinder 42 has a spiral groove 43 cut on the surface thereof, and a pin 44 depends from the carrier 31 and extends into the groove, thus causing the carrier to reciprocate as the cam cylinder is rotated. A shaft 45 extends from the cam cylinder and is driven from a suitable source of. power, not shown.
